In this photo, you can see multiple layers of both hard and soft rock formations. The cap on the dramatic toadstool formation is a boulder of Cretaceous-age Dakota Sandstone. This cap prevents the complete erosion of the softer red Entrada sandstone from the Jurassic age. The other patterns are formed by both water and wind with the residue forming the sand dune in the lower right of the photo. Part of the enjoyment of looking at this type of landscape is understanding the forces that created it.
